Alex Lewington, Tomas O'Leary, Ofisa Treviranus and Kieran Low are the only survivors from Exiles' 70-14 win over Rovigo at Madejski Stadium last Sunday.

But six of the Irish team that started against the Italian part-timers - hat-trick hero Topsy Ojo, Eoin Griffin, Conor Gilsenan, Dan Leo, Jimmy Stevens and Matt Parr - did enough to earn a place on the bench tomorrow.

Grenoble, currently seventh in France's Top 14 table, have won all five of their home games this season and are expected to provide a much stiffer test than Rovigo.

Shane Geraghty will captain Exiles in the absence of George Skivington, one of only three players who started the 44-24 Premiership defeat at Exeter Chiefs a fortnight ago not recalled into the 23-man squad.
